Hi all,

as indicated by Jakub Zawadzki, there was a Nmap GSoc 2013 project porting
Winpcap to NDIS 6, with the source code found here:
After a quick test, I can confirm that:
- interfaces are now seen and can be selected for capture
- ethernet frames containing TCP packets are seen with a size of 2048 bytes
(while I have a MTU set to 1500) and the extra data is seen as ethernet
trailer of 570 bytes + a FCS of 4 bytes
- DNS queries are truncated (only the first 8 bytes of UDP datagram are
So this is not yet usable but seems to be a good starting point.
http://seclists.org/nmap-dev/2013/q4/108 suggests that the code was shared
with WinPcap development team (or at least this was the intention). Did
this ever happened?

Best regards,
